Poinsettia plant named ‘Qismas Crunch’

ABSTRACT

A new and distinct cultivar of Poinsettia plant named ‘Qismas Crunch’, characterized by its compact, upright and uniformly mounding plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves that are twisting and “curly” in appearance; large and full inflorescences with numerous dark red-colored flower bracts; and excellent post-production longevity.

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘QISMAS CRUNCH’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as Euphorbia pulcherrima Willd. and hereinafter referred to by the name ‘Qismas Crunch’.

The new Poinsettia plant is a product of a planned breeding program conducted by the Inventor in Sabro, Denmark. The objective of the breeding program is to create uniform and freely-branching Poinsettia plants with attractive inflorescences and good postproduction longevity.

The new Poinsettia plant is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ‘Eckalverta’, disclosed in U.S. Plant Pat. No. 13,297. The new Poinsettia plant was discovered and selected by the Inventor as a single flowering plant within a population of plants of ‘Eckalverta’ in a controlled greenhouse environment in Sabro, Denmark in May, 2011.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Sabro, Denmark since September, 2011 has shown that the unique features of this new Poinsettia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Poinsettia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Qismas Crunch’. These characteristics in combination distinguish ‘Qismas Crunch’ as a new and distinct Poinsettia plant:

-   -   1. Compact, upright and uniformly mounding plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely branching habit.     -   4. Dark green-colored leaves that are twisting and “curly” in         appearance.     -   5. Large and full inflorescences with numerous dark red-colored         flower bracts.     -   6. Excellent post-production longevity.

Plants of the new Poinsettia can be compared to plants of the parent, ‘Eckalverta’. Plants of the new Poinsettia differ primarily from plants of ‘Eckalverta’ in the following characteristics:

-   -   1. Plants of the new Poinsettia are more compact than plants of         ‘Eckalverta’.     -   2. Leaves of plants of the new Poinsettia are “curly” whereas         leaves of plants of ‘Eckalverta’ are flat.     -   3. Flower bracts of plants of the new Poinsettia are more         horizontal and twisting than and not as upright and flat as         flower bracts of plants of ‘Eckalverta’.     -   4. Plants of the new Poinsettia have shorter peduncles than         plants of ‘Eckalverta’.

Plants of the new Poinsettia can be compared to plants of Euphorbia pulcherrima Willd. ‘Happy Day’, not patented. In side-by-side comparisons conducted in Sabro, Denmark, plants of the new Poinsettia differed primarily from plants of ‘Happy Day’ in the following characteristics:

-   -   1. Flower bracts of plants of the new Poinsettia were more         twisting than and not as flat as flower bracts of plants of         ‘Happy Day’.     -   2. Flower bracts of plants of the new Poinsettia had entire         margins with pointed lobes whereas flower bracts of plants of         ‘Happy Day’ had entire margins without lobes.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Poinsettia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Poinsettia plant.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Qismas Crunch’ grown in a container.

The photograph on the second sheet is a close-up view of a typical dissected inflorescence of ‘Qismas Crunch’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the winter in 13-cm containers in a glass-covered greenhouse in Sabro, Denmark and under cultural practices typical of commercial Poinsettia production. During the production of the plants, day temperatures ranged from 20° C. to 25° C., night temperatures ranged from 19° C. to 21° C. and light levels ranged from 40 to 50 klux. Plants were pinched one time eight weeks after planting and plants were 20 weeks old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
